Abstract

A patient supported on a patient support (12) is moved into a bore (22) of a planning imaging device, such as a CT scanner (20). A three-dimensional diagnostic image in three-dimensional diagnostic image space is generated and stored in a memory (130). The patient is repositioned outside of the bore with a region of interest in alignment with a real time imaging device, such as a fluoroscopic imaging device (40). A surgical planning instrument (60), such as a pointer or biopsy needle (62), is mounted on an articulated arm (64). As the instrument is inserted into the region of interest, fluoroscopic images are generated and stored in a memory (140). The coordinate systems of the CT scanner, the fluoroscopic device, and the surgical instrument are correlated (102, 104, 112, 120) such that the instrument is displayed on both the CT images (134) and the fluoroscopic images (50), such that cursors move concurrently along the fluoroscopic and CT images, and the like. In a preferred embodiment in which the cursor on the CT image display is at an intersection of transverse, sagittal, and coronal planes, the displayed planes change as the cursor moves coordinating the displayed CT image planes with the position of the cursor on the fluoroscopic image.
